Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Canon IXUS 165 and Panasonic FH5 side-by-side from the front, back and top in their relative dimensions. Canon IXUS 165 has external dimensions of 95 x 54 x 22 mm (3.74 x 2.13 x 0.87″) and weighs 128 g (0.28 lb / 4.52 oz) (including batteries). Panasonic FH5 has external dimensions of 94 x 54 x 19 mm (3.7 x 2.13 x 0.75″) and weighs 121 g (0.27 lb / 4.27 oz) (including batteries).

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
Panasonic FH5 is 7g lighter than the Canon IXUS 165 but we don't think this will make a significant difference.
